After lurking around Channel9 for quite some time now, I think it's time to step out of the shadows and actually post something. So here goes:
I wrote a complete implementation of LINQ to Objects in JavaScript (but you already know that because you've read the title).
What does complete mean? Well, it means two things:
a) System.Linq.Enumerable is there (except it's called jsinq.Enumerable) and it has all the same methods... all of them (except those related to casting which don't really apply to JavaScript)
b) There's a query compiler that allows you write queries in LINQ-syntax.
c) (Did I say two things, I mean three) If you know LINQ (to Objects) and JavaScript, you know JSINQ!
But don't take my word for it, try it yourself! (Yes, I do watch a lot of infomercials, why do you ask?)
So you can almost write something like this:
from customer in $0
group customer by customer.lastname into g
select {lastname: g.getKey(), count: g.count()}
into r
orderby r.count descending
select r
Except you have to put quotes around it (so it's not really Language INtegrated Query, more like Language bolted-onto Query). But it's still really useful and it's free (as in MIT-licensed), so get yours now!
More importantly though, tell me what you think and please report bugs if you should find some.
